What I haven't heard mentioned yet is, that for the big companies like Google and Facebook, there won't actually be much change in regards to upload filters, because they already do this. The DMCA has led to quite a similar problem for them, so that for example youtube provides big license holders with backend to decide themselves which videos to block for reasons of copyright infringement. So in the end, they wont even have to do anything, they already have the infrastructure in place to overblock and have indeed done so for many years. But at the same time, where this becomes really disastrous is smaller communities, where admins and moderators have no chance of checking every post themselves for violations and neither the technological means to do it automatically. In Germany at least, this was from time to time reason for lawsuits but until now, the consensus of the courts was, that it is enough for the admin to remove the offending content after he was made aware of it. This changes now of course, which makes it practically impossible to offer these kind of services if you are not a big company with huge resources. I know Forums and the like are not as far spread as they once were, but this will make it practically impossible to create these kind of communities.
